Q Light Controller+

I tried today to do this with a kinda result with the speed widget. So I am trying to assign a external fader to control efx movement speed in VC. I am trying to have a level on the fader at 0 is no movement then the movement gets faster as you raise the fader.

I successfully have done that - but the solution lies with having 1 slider (bound to external control) and controlling a loopback channel (controlling the speed of time widget). This slider is limited to the values you want to have.
